NGC 7293 = Helix Nebula - Revisited #2

This is another attempt at imaging the Helix Nebula - exactly a year to the day after my previous image, and two years to the day since my first attempt.

This was a challenging image to process ...
The Moon was at 98%, so the image had a very strong gradient, and I was experimenting with Gain and Exposure settings, so these subs were quite short at 60s each, and turned out to be very noisy.

Pre-processed and stacked using Affinity Photo, further processed using Star Tools to improve image quality, then fine-tuned using Affinity Photo.

Description: I felt that the bright star HD212890 was a bit distracting, so I enlarged and cropped the image slightly to focus on the nebula.

Uploaded: ...

D

Description: My goal for this revision was to reduce the size of some of the brighter stars, and develop the fine detail in the central region of the nebula.

Reducing the brightness of the larger stars has sacrificed detail in the smaller stars, so I will develop another revision that strikes a better balance between the two.

This revision was re-stacked and processed entirely using Affinity Photo.

Description: With this revision, I've tightened the brighter stars, and enhanced the fainter stars, while restoring a more natural colour balance to the star field.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
